| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "img,pistachio-gptimer". |
| 5 | - reg: Address range of the timer registers. |
| 6 | - interrupts: An interrupt for each of the four timers |
| 7 | - clocks: Should contain a clock specifier for each entry in clock-names |
| 8 | - clock-names: Should contain the following entries: |
| 9 | "sys", interface clock |
| 10 | "slow", slow counter clock |
| 11 | "fast", fast counter clock |
| 12 | - img,cr-periph: Must contain a phandle to the peripheral control |
| 13 | syscon node. |
| 14 | |
| 15 | Example: |
| 16 | timer: timer@18102000 { |
| 17 | compatible = "img,pistachio-gptimer"; |
| 18 | reg = <0x18102000 0x100>; |
| 19 | interrupts = <GIC_SHARED 60 IRQ_TYPE_LEVEL_HIGH>, |
| 20 | <GIC_SHARED 61 IRQ_TYPE_LEVEL_HIGH>, |
| 21 | <GIC_SHARED 62 IRQ_TYPE_LEVEL_HIGH>, |
| 22 | <GIC_SHARED 63 IRQ_TYPE_LEVEL_HIGH>; |
| 23 | clocks = <&clk_periph PERIPH_CLK_COUNTER_FAST>, |
| 24 | <&clk_periph PERIPH_CLK_COUNTER_SLOW>, |
| 25 | <&cr_periph SYS_CLK_TIMER>; |
| 26 | clock-names = "fast", "slow", "sys"; |
| 27 | img,cr-periph = <&cr_periph>; |
| 28 | }; |
